altium pcb library using existing footprints

The typical process for designing PCB footprints and schematic symbols from your datasheets is shown below. Many datasheets will include physical dimensions for PCB footprints and pin diagrams that can be used to create schematic symbols. If you’ve been involved in the systems design process, then you probably have datasheets available for your desired components. If your current job description is “PCB Librarian” or you have a backlog of component models, you can usually open an old model and create a new PCB footprint for your desired component.īelow you can find two common options for creating PCB footprints. You would then have to import them into your CAD software and create library files for your components. In the past, you would have to open up a CAD application and create schematic symbols and footprints yourself. Once you’ve decided on the critical components you need for your new system, you’ll need to rummage through your libraries and determine which footprints you need to create. PCB Footprint Creation Guidelines and Process To create symbols and footprints for your new design, follow these PCB footprint creation guidelines and processes. There are a few options available to quickly create or purchase components for your system. When you need fast access to a large number of components, and you don’t have them in your library, where can you get them quickly? Of course, finding these components is only half the battle: verifying their accuracy across footprints, ensuring availability and cost, as well as delineating clear mechanical constraints are necessary too. Everything from form factor to sourceability needs to be considered during the initial design phase, especially if you want to avoid redesigns and long manufacturing delays. Before you create your schematic, you need to know which components will power your system and provide the desired functionality. If you’re designing a new electronic product, it all starts with component selection.

Your components are like the backbone for your new system and your new product won’t function without the right components. Follow our PCB footprint creation guidelines if you want your 3D layout to look this great.
